MG2-100 is a navigation-grade micromachined single-axis MEMS gyroscope. It provides high-precision north seeking angle rate measurement, its power consumption is very low, the bias stability (Allan variance) is only 0.02°/h, and the bias stability (1σ 10s) is only 0.1°/h. The MG2-100 is optimized for high accuracy and stability. MG2-100 is specially designed for north seeking. The advanced differential sensor design rejects the influence of linear acceleration. Angular rate data is represented as 24-bit words. It comes in a hermetically sealed ceramic LCC surface-mount package and is capable of operation over a 5V supply and a wide temperature range (−45°C to +85°C). https://www.ericcointernational.com/gyroscope/mems-gyroscope/er-mg2-100-north-seeking-mems-gyro.html

MEMS gyroscope MG2-100 is available in a compact 11 x 11 x 2mm package. When the gyroscope is in fully operational mode, power consumption is typically 40mA. It is mainly used in oil drilling, aviation and other fields. At the same time, it can be placed in IMU (Inertial Measurement Unit), north finder, gyro compass, drilling tools and inertial navigation system. Due to its high performance, MG2-100 can also be used for high-precision attitude measurement, stability control, positioning, navigation-grade MEMS IMU/INS, land surveying/land mobile mapping systems, railway train systems, etc. As an advanced differential sensor design, it suppresses the effects of linear acceleration, allowing it to operate in extremely harsh environments where shock and vibration are present.
◾ Application
1. Oil and gas fields
Gyroscope measurement is an essential part of drilling, and the worst environment for gyroscope use is in the oil and gas downhole drilling industry.
MG2-100 MEMS gyroscope uses a solid-state sensor design that can withstand extreme conditions such as downhole shock and vibration. It does not require recalibration during use and consumes less energy. The same battery can last longer. The embedded gyroscope MWD of MG2-100 can meet the accuracy requirements required by today's complex drilling environment, and due to its high accuracy, when used in conjunction with MWD tools, the uncertainty can be reduced by 45%, which is conducive to precise measurements.
2.Aerospace
Because aerospace technology has very high requirements on the functional density ratio of devices. In aerospace and aerospace applications, high-precision interferometric fiber optic gyroscopes are commonly used.
MEMS gyroscope MG2-100 compared to FOG (Fiber Optic Gyroscope) can achieve the same high accuracy as FOG, but is much smaller, has lower emission quality, and is cheaper with lower power consumption to maintain temperature. It can be used in attitude and heading reference systems, flight control systems, modal testing, etc. in aerospace applications.
